Application filed May 26, 1915. Serial No. 30,644.

To all whom it may concern:

Be it known that 1, Leo L. HENRY, a citizen of the United States, residing at Cedar Rapids, in the county of Lin and State of Iowa, have invented a new and useful Paper Box, of which the following is a specification.

The present invention appertains to paper boxes, and relates more particularly to that class of boxes employed for holding suits of clothes, and the like.

The object of the invention is to provide novel and improved means for fastening the side and end walls of the box together, whereby the box will be substantial in construction, easy to manufacture, and foldable into a flat condition so that a number of the folded boxes may be compactly shipped, stored and handled.

With the fore oing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a plan viewof the blank from which the box is formed. Fig. 2 is a perspective view of one corner portion of the box. Fig. 3 is an enlarged sectional detail taken on the line 3-3 of Fig. 2. Fig. 4: is a fragmental plan view of one corner portion of the box in folded position.

Boxes of the present character usually embody a receptacle or tray and a cover which are of duplicate construction. whereby one may be slipped upon the other, but for the purpose of the present disclosure, only one part or section of the box need be illustrated and described in detail. The box is constructed of paper, cardboard, or other equivalent material, and may be constructed in various sizes and proportions. The box or receptacle embodies a bottom 1 having the upstanding side and end walls 2 and 3, respectively. The end walls 3 are provided at their upper edges with reflexed flanges or flaps 1 bent back inwardly, said flanges be ing relatively narrow and flexible. V

The ends of the side walls 2 are provided with flaps 5 bent at right angles with the .faces of the end walls 3. of the flaps 5 are tucked in under the flanges side walls 2, and resting against the inner The upper edges 1, and the flaps 5 are provided with diagonal or inclined scores or fold lines 6 extending from the corners of the bottom 1 to the opposite corners of the flaps 5.

The free ends of the flaps 5 remote from the side walls 2 are provided with outstanding tabs 7 at those corners of the flaps 5 remote from the corners of the bottom 1, and the tabs 7 fit under the flanges at, or between the said fianges and end walls 3. The tabs 7 are in turn provided with supplemental tabs 8 projecting therefrom along the free ends of the flaps 5, cuts or slits 9 being provided between the supplemental tabs 8 and the flaps 5, and scores or fold lines 10 being provided between the tabs 7 and supplemental tabs 8 whereby the supplemental tabs 8 may be bent back or folded upon the tabs 7. The supplemental tabs 8 are bent back against the flanges 1 so as to project upwardly, as clearly seen in Figs. 2 and 3, and staples or other securing elements 11 are engaged through the suplemental tabs 8, flanges 1, tabs 7, and end walls 3, whereby said parts will be securely clamped together. In this manner, the flaps 5 are fastened in a thoroughly simple, yet efficient manner to the end walls, and the flaps 5 may be slipped from under the flanges 4 when the box is folded.

lVhen the box is erected, the flaps 5 fitting under the flanges 1 will be held by said flanges against the end walls 3, so that the box will be thoroughlv substantial. When the box is folded, the flaps 5 are snapped or moved from under the flanges 4, whereby the end walls 3 may be swung outwardly into the plane of the bottom 1, and whereby the side walls 2 may be swung inwardly upon the bottom, as illustrated in Fig. 4, the flaps 5 being folded or doubled upon the fold lines 6.

The present box does not involvev any appre'ciable waste in material, since the only parts of the stock which are cut away, are the small portions between the flanges 4 and supplemental tabs 8. Otherwise, the blank is of perfectly rectangular contour. The blank may be readily cut from the stock, and may be foldedeasily to provide the box or receptacle.

lVhat is claimed is:

1. In a box, a pair of walls, one having a refiexed flange, and the other having an angularly extending flap fitting under said flange, said flap having a tab projecting therefrom under said flange, and said tab having a supplemental tab bent back therefrom, and a securing element engaged through the tabs, flange and first mentioned Wall.

2, A folding box embodying a bottom having a pair of upstanding Walls, one provided at its edge With an inwardly refieXed flange and the other having an angularly extending flap in its respective end, the upper edge of said flap fitting under said flange, said flange being flexible, said flap having a fold line extending diagonally Copies of this patent may be obtained for five cents each, by addressing from the respective corner of the bottom to the opposite corner of said flap, said flap having a tab projecting from its free end at the last mentioned corner thereof and fitting under said flange, said tab having a supple mental tab bent backwardly against said flange, and a securing element engaged through said tabs, flange and first mentioned Wall.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.
